Soon, Mars and the others came to the ground and took a breath of fresh air, Isolde frowned slightly: "The Super God Sacrifice Magic Array seems to have been modified, maybe it is a god, it seems that this place has really become a slaughterhouse!"

Mars understood Isolde's thoughts very well, he was a sage, he was of noble character, he naturally had a natural sensitivity to evil, and he hated such evil even more, he said: "All right, Aesop, now is not the time to be sad, let's go to the treasure house!"

Immediately, a fierce gaze erupted in his eyes, "By the way, destroy a few big demon bases!"

Erin's eyes also showed a look of resentment, and she said, "Before the Great Demon Clan's Holy Rank reacts, this can be done!"

And Crazy Iron looked indifferent, anyway, he felt that even if he killed a few Great Demon Clan Holy Ranks now, it would only be a drop in the bucket, and there were so many Great Demon Clan's Holy Ranks.

Isolde did not object, obviously he still had hatred for the Great Demon Clan, after all, it was the arrival of the Great Demon Clan that caused the Dragon Servant Clan to be wiped out.

He slightly discerned the direction and said, "My lord, I have determined the direction of the treasure house, and you follow me!"

Mars agreed, and as Isolde rose into the sky, he quickly headed in one direction.

How big is the space battlefield? So far, there is no specific figure, but we only know that this is a very vast landmass, and due to the special geographical environment, there is no clear direction for Lapse here, but some special terrain as the direction.

For example, in the Redstone Mountains, there are two bases of the Great Demon on one side and two bases of Lapse on the other side.

Mars and the others followed Isolde along the side of the Great Demon Base in the Redstone Mountains, and by the way, destroyed the two bases in a very short period of time.

To Mars's surprise, each of these two bases had two Holy Ranks, so they quickly killed four Great Demon Saint Rank powerhouses and left.

When the Great Demon Clan's Saint Rank powerhouse found out, Mars and the others had already come to the bank of a river.

This is the largest river in the space battlefield, and no one knows where it comes from and where it eventually flows, because there are several sections of this river that flow underground.

Therefore, the river is called the River Styx, which means that the river eventually leads to the legendary underworld.

Looking at the pale black river, which is hundreds of meters wide, Mars actually has a feeling of palpitations.

"Why does this river Lao Tzu feel in danger?" said Crazy Iron with a puzzled expression.

Isolde nodded and said: "This river water has a corrosive effect, the further down, the greater the corrosion intensity, even the protective shield formed by the mana and fighting qi of the saint-rank powerhouse is difficult to resist, and the treasure house is somewhere in this river." ”

Crazy Iron suddenly became unhappy, "Since this river water is so corrosive, then how can we go down? You bad old man is really bad, you want to kill us!"

Mars frowned slightly, and scolded: "Crazy Iron, can you keep your mouth shut? Since Aesop is loyal to me, he naturally has a way, can you stop for a while?"

"Ah, my lord, I just thought that this guy was going to sacrifice us in the first place, and I couldn't get angry...... Yes, my lord, I'll shut up!" Madiron saw that Mars's face was a little unkind, and immediately closed his mouth.

Isolde was not annoyed, he smiled faintly and said, "My lord, as I said earlier, my lord has already obtained the key to the treasure house, so ......"

Mars smiled slightly, suddenly showed a sense of understanding, took out the artifact, and said, "I know, you all surround me!"

Isolde and Erin didn't hesitate at all, and stood beside Mars, and Crazy Iron was stunned for a moment, but when he saw Mars's face, he also muttered and stood up.

Immediately, Mars Divine Thought Communication Artifact, and the artifact suddenly shot out a white beam of light, instantly enveloping everyone, and then under Mars's command, the artifact rolled up everyone and rushed into the pale black river.

And just a moment after Mars and the others disappeared, a great demon magician showed his figure, his forehead was full of beads of sweat, he wiped the sweat, his eyes glanced around, and suddenly said suspiciously: "Treasure house? There is a treasure house in this water? No, no, the strength of these four people seems to be too strong, they have to report to the general, maybe they will make a great contribution!"

Immediately, his figure disappeared again.

Besides, Mars activated the artifact and rushed into the river, and soon came to the bottom of the river, but with the protection of the artifact shield, the strong corrosiveness of the river water had no effect, but the wild iron was always startled, which made Mars and Erin despise it very much.

Once at the bottom of the river, Isolde got serious, he recognized the markers at the bottom of the river from memory, and then all the way down, they went underground, then to the surface, and then into the ground...... In short, the itinerary is more complicated than expected.

It wasn't until he came to an underwater canyon that Isolde carefully identified it, and then said: "It should be here, it was an ice dragon that guarded this place back then, it was a very powerful one, but the ice dragon finally followed the dragon clan away, and there was no dragon protection here, and then the artifact key was set up, only the holder of the artifact can enter, however, there are some traps set up inside, but it has no effect on the holy rank powerhouse, Brother Crazy Iron, you are responsible for these traps, my lord, let's go in!"

Crazy Iron was about to refute, but when he saw Mars's cold eyes, he suddenly wilted, and promised, "Got it!"

So, Mars urged the artifact and entered the canyon, which seemed to be another space, where no river flowed.

"Woo woo woo ......"

Suddenly, a sound of breaking wind sounded, and tens of thousands of crossbow arrows flew densely, and Crazy Iron snorted coldly, and a huge shield in his hand was condensed, protecting Mars and the others.

"The crossbow bolts are not powerful enough to hurt the Holy Order!" Mars said lightly, his heart suddenly relieved, Isolde was not wrong.

In this way, they continued to move forward, encountering dozens of traps along the way, but none of them were too powerful, and Crazy Iron was able to do it alone.

"Is this the treasure trove?" said Iron, disdainfully.

In front of everyone's eyes is a rock wall with a stone cave with a closed door and the word "treasure house" written on it.

Isolde's eyes crossed a slight trace of remembrance, but he quickly calmed down, he sighed lightly, and said: "My dragon clan has thousands of years of history, there are dozens of treasure houses, but it is a pity that part of it was taken away back then, part of it was obtained by your orc clan, and the other part was obtained by the big demon clan, and the remaining one is also the last treasure house, which is just the savings of the dragon clan for more than two hundred years." ”

"Aesop, don't be sad, the rise and fall of every race has its own reason, just like the Lapus races, the glorious civilization of the past, the collapse is only a matter of a few hundred years...... How do you get this in?" Mars said.

Isolde's eyes became calm, and he said, "What the Lord said is reasonable...... It's okay for adults to push the door directly, after all, if there was no artifact here, you can't get here at all, so there are no security measures on the door. ”

Mars looked at Erin, Erin nodded, and Mars took the artifact and pushed it directly towards the stone door.

"Boom ......"

With a loud bang, the stone door slowly opened.
